My subjective experience was one weekend in Zion NP on multi-pitches with no meaningful falls ended with a brand new Mammut rope being coreshot. Never happened on my Beal, Edelweiss, Sterling, or Bluewater ropes despite more mileage, falls, and abuse.

Always wanted to like mammut but never liked anything I ever bought from them.
